This really doesn't have anything to do with listening so please forgive me but I reakky want to know. I'm looking at a list of flights that are supposed to arrive at JFK one of them is Alaska airlines 1270. Is there a reason im not seeing this flight on JFK's current flight map? All other flights are showing up.

Don't know where you're looking but on flightstats you can find the following:

MY NOTE: It is a codeshare flight and may not show up in tracking as Alaska Airlines 1270. It should, however show up in tracking as American Airlines 20. The last time a flight track was shown for Alaska Airlines 1270 on flightstats was sometime end of May.

I don't really understand what you mean? I saw American 20.. But also the Alaska flight, and soem Qantas flight were due same time and all showed the same info but only the American 20 fight was shown.

codeshare |ˈkōdˌ sh e(ə)r| nouna marketing arrangement in which two airlines sell seats on a flight that one of them operates : [as adj.] Qantas is a codeshare partner with both American Airlines and Alaska Airlines in North America.• a flight or aircraft in which such an arrangement is in effect.

Airlines may sell flights operated by other airlines: http://en.wikipedia.org/wiki/Code_share It shows up under all flight numbers at the airport, but it is only one plane that flies and ATC only uses the flight number of the operating carrier. (In Europe ATC flight numbers can be completely different from the numbers shown to the passengers.)
